Hello Everyone
Need some advice here

My Current System :
Celeron 2 giga, 512 Mb DDR1
Hdd 20G IDE
PFSense 1.2 BETA
2 Interfaces WAN and LAN
Captive Portal ON with free radius
approx. 70 users are logged in simultan.
30+ users are pass MAC through
the rest is mobile user with laptop
Add-on installed:
Squid, Free Radius

Here my Process list:

ps uax

USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 10 40.1 0.0 0 8 ?? RL 12:39PM 7:39.49 [idle: cpu0]
root 13011 14.5 3.1 18996 15860 ?? S 1:20PM 0:02.89 /usr/local/bin/php
root 12988 12.4 3.0 18320 15192 ?? R 1:20PM 0:07.94 /usr/local/bin/php
root 12782 11.0 3.5 20724 17620 ?? S 1:19PM 0:14.95 /usr/local/bin/php
root 12832 10.0 3.5 20724 17620 ?? S 1:19PM 0:11.04 /usr/local/bin/php
(complete list in attachment - process.txt)

these 4 processes always on this state of load, sometimes it could rise up to 100% of CPU load
(I've taken a screen shot of RRD Graph - cpuload.jpg)

QUESTION :
Is it normal to have this kind of process load in my system? :
